SHUTTLE Specification of Letters Patent.

PatentedNov. 5, 1907.

Application filed April 6. 1907. Serial No. 366,802.

To all 'whom L may concern:

Be it known that l, JAMES A. GALLAGHER, a citizen of the United States,residing at Lancaster, in the county of Lancaster and Statel ofPennsylvania7 have invented new and useful Improvements in Shuttles, of

n which the following is a speciiication.

This invention relates to shuttles for weaving machines and relates moreparticularly to a drag replenishing device for the shuttle.

According to the usual practice, a shuttle is provided with a drag inthe orm of a small piece of woolen yarn that is inserted through an eyein the shuttle and pegged fast thereto. Since the drag is quickly wornaway, new ones have to be substituted from time to time and to do this,the loom fixer takes out the peg and puts in a new drag. This operation,besides being tedious, takes a great deal of time, and as the drags haveto be renewed every day or oftener, a considerable expense is attachedto keeping the shuttles in repair.

The present invention has for one of its objects to overcome theobjections above referred to by providing a drag replenishing device,whereby the drag can be renewed from 'time to time by the weaver in asimple and expeditious manner.

A further object of the invention is the provision of a spool mounted inthe shuttle on which the woolen yarn is carried, one end of which beingprotruded from the body of the shuttle to operate as a drag.

A further object of the invention is the employment, in connection witha spool-carrying drag, of a brake whereby the spool is prevented fromunwinding except when the yarn on the spool is deliberately pulled orunwound by the weaver to provide a new drag.

With these objects in view and others7 as will appear as the descriptionproceeds, the invention comprises the various novel features ofconstruction and arrangement of parts which will be more fully describedhereinafter and set forth with particularity in the claims appendedhereto.

ln the accompanying drawing, which illustrates one of the embodiments ofthe invention, Figure l is a plan view of a shuttle. Fig. 2 is a sideelevation thereof partly in section. Fig. 3 is a.fragmentary sectionalview of the drag-carrying spool and brake therefor drawn on an enlargedscale. Fig. 4 is a side view of the spool of the drag replenishingdevice.

Similar reference characters are employed to designate similar partsthroughout the several figures of the drawings. i

Reierring to the drawing, l designates the shuttle in which is arrangedin the usual manner the weaving spool 2. At one end of the shuttle is achamber 3 that is open at one side as indicated by 4, lfig. 3, forpermitting of 'the removal and insertion oi the drag-carrying spool 5.'lhis spool is held in place by a screw 6 that serves as a pivot onwhich the spool turns; Wound on the spool is a woolen yarn or othersuitable material designated by 7, whose inner end is fixed to the spoolby engaging under the pin 8. The yarn 7 passes outwardly from thechamber 5 through a guide 9, the free end of the yarn forming the drag.The spool is of sulicient capacity that the yarn wound thereon willserve to form any desired number of drags by pulling or unwinding theyarn step by step as the drags wear away and require to be renewec..

In order to hold the spool 5 stationary, so that the yarn 7 will notautomatically unwind, a suitable brake device is employed for yieldinglyengaging the spool. "he body of the shuttle is provided with a recess l0arranged tangentially to the spool and in this recess is a, leaf springll. that bears on the periphery of the spool. This spring is held inplace by a screw 12 extending into the body of the shuttle from the top,as shown in Fig. l. The free end ot the spring or brake ll is accessiblethrough the open side 4 of the chamber 3 so that the spring can beengaged by the finger and moved out of the way oi the spool when thelatter is removed or supplying another yarn. To remove the spool7 thescrew 6 is taken out and the spool can then be slipped bodily out of theopen side 4 of the chamber ln order to enable the attendant to grip theworn end oi the yarn7 the body of the shuttle is provided with a slot 13at the outer end of the guide 9, whereby the attendant can insert thethumb and rst linger into the slot to take hold oi the end of the yarnwhen a new drag is to be made. Y

From the foregoing. description taken in connection with theaccompanying drawings7 the advantages o the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains. ln operation, the parts are in theposition shown in Fig. 3. When the ree end of the yarn 7 becomes worn,the attendant takes hold oi the yarn and pulls outwardly on the saine sothat the spool 5 unwinds. This positive pull on the yarn Will cause thebrake ll to yield, and as soon as the attendant ceases pulling on theyarn, the brake will positively hold the spool. The yarn is pulled outsufficiently to form a drag. This operation is 'repeated from time totime as the drag has to be renewed.

l have described the principle of operation of the invention, togetherwith the apparatus which l now consider to be the best embodimentthereof, and desire to have it understood that the apparatus shown ismerely illustrative and that such changes may be made when desired, asare within the scope of the claims.

Having thus described the invention, what l claim isz-- l. Thecombination with a shuttle, of a drag replenishing device mounted on theshuttle, said device comprising means for holding a supply ot' dragforming,l material, and means for permitting the material to be drawnout piece by piece for renewing the drag.

2. '.Lhe combination with a shuttle, a drag-carrying,l spool mountedtherein, and means for yieldingly holding the spool stationary.

3. The combination of a shuttle, a removable spool therein, a drag yarnthereon, and a brake in the shuttle for yielding-ly holding the spoolstationary.

4. The combination of a shuttle, a drag-carrying,l spool, a screw pivotfor holding the spool in place, and a spring arranged in the shuttle toengage the spool to form a Drake therefor.

5. The combination of a shuttle provided with a chamber open to oneside, a drag-carrying spool removable through the open side of thechamber, a pivot for holding the spool in the chamber, a guide for thedragY through which the latter is drawn from the spool, and a brakereleasably engaging the spool.

6. The combination of a shuttle having a chamber' 'open ing at one side,a drag-carryingl spool in the chamber and removable from the open sidethereof, a removable pivo.t for the spool, a guide through which thedrag is drawn from the spool, and a spring arranged in the chamber toengage the' periphery of the spool andlhaving its free end accessiblethrough the open side ot' the chamber.

In testimony whereof, I affix my signature in presence of two witnesses.
